To all `whom t may concer/nf.'

e it known that I, DUDLEYNEWTON, a citizen of the United States,residing at San Francisco, in the county' ofSa'n Francisco 5 and yStateof California, have invented new and useful Improvements A in Devicesfor Flushing `Toilet Fixtures, of which the following is aspecification.

The present invention relates to apparatus for automatically flushingtoilet fixtures such as water closets, urinals and the like and hasspecial regard to certainimprovements in apparatus of the characterembodied in United States Letters Patent, Numbers 1,201,752` andv1,328,445, issued to me on Oct. 17, 1916,and J an. 20, 1920,respectively. The primary object of the invention is to provideapparatusof the character described which will be more simple as toconstruction, less expensive, more compact, easier to install and takedown and also easier to clean, than similar apparatus heretofore used;these objects being attained principally thru the use of a novel andsimplified form of sipho-n apparatus and by reasonv of the manner ofhousing and positioning or the locat ing of the same. v

The invention possesses other advantages and features some of which,with the foregoing [will be ,set forth atlength in the followingdescription where I shall outline in full that form of the inventionwhich I have selectedv for illustration in the drawings accompanying andforming a partof the present specification.' In said| drawings I haveshown one form of the construction of my invention, but it is to beunderstood that I do not limit :myself to such form since the inventionas expressed in the claims may beembodied in a plurality of forms.

yReferring' to the drawings; F'gure 1 is a fragmentary verticalsectional view of the apparatus of this invention shown applied to aurinal. Figure 2 is an enlarged vvertical fragmentary section` thru theflushing tank taken at right angles to Fig. 1.

The present embodiment ofthe invention as shown in the ,drawingscomprises aurinal 1 of porcelain, supported on the usual back or wallslab 2 behind which is a flushing tank 3 supported in any suitableina-nner above lthe urinal. The tank 3 contains lthe usual filling andlevel control apparatus, not

shown.

comprises a Icover 5 or airfcontainer thru ythe top of which an airinlet pipe extends .leg leads to and is formed integral with 'a trap 8.Asho-rt pipe QcO-mmunicates ywith the outlet endof the trap, extendsthru t.he back 2 and is connected with a yflushing pipe 10 which latterextends into the top of the urinal.

A pipe llkleadsfrom the inlet side of the trap 8 downwardly, thenthru-'the back 2 at a point below ythe urinal and then kupwardly as at12 whereby a trap as shown at 13 is provided inthe pipe 11. The lowerside of the porcelainurinal 1 is enlarged and thickened as at-14, andhas an outle-t or discharge opening 15 therein, A perforated screen orguardi plate y16is removably fitted in a countersink 17 in saidopening.v A drain or outlet passage l1 E5`yis provided in the portion`14and is of less diameter than the opening 15,1s'o as to provide fortheformation-'of siphoni elements below but in registration withsaidopening 15V. A drain pipe 19 is connected in the usual V y A Siphonis'inounted in the tank 8,- and manner with the urinal` andy registers`with y the passage 18. e Y n y,

Siphon ymeans is housedl within the len,-A larged portion-14 oftheurinal and comprises a rectangular chamber 20 having'lits from thecore portion 24 and from the guard plate 16.

A siphon conduit 25 is formed in the core portion 211 and extends thruthe portion 14 to the lower side thereof, where it is co-nnected as at26 with the upper end of the pipe 11. A similar condluit 27 is formed inthe portions 14k and 24 and leads into the lower end of the drainpassage 1S. The up` per ends of these passages 25 and 27 areapproximately in the same plane at the top of the core 24 which latterterminates below the cover. The passage 25 is virtually an extension ofthe pipe 11 and a part of the trap 13.

Operation.

After a. iushing operation and the tank is empty, the water is left atthe level of the pipe 9, in the trap 8, and the pipe 11 draws the waterfrom the intake side ofthe trap whereby the water in both sides of thetrap is brought tc the same level, namely, the top of the pipe 11. Thepipe 11 conducts the water to the trap 13, to the upper end of thepassage 25 from which the water spurts or flows with sufficient forceagainst the cover plate 16 to dislodge any foreign matter which may havebeen lodged in the' chamber 20. This also prevents clogging of thepassage 25 and other siphon elements in the urinal, as these parts arethoroughly flushed by the action above described, after the flushing ofthe urinal. After the trap 8 is drained to the level of the top of thepipe 11, the level of the water in the pipe 11 descends until it reachesthe level at the top of the passage 25, or in other words, balances inthe trap 13. The water in the chamber 2O both on the inside and outsideof the cover will siphon out thru the pipe 27 and the level thereof willbe brought below the upper ends of the conduits 25 and 27.

lVhen the tank 3 begins to lill, air which has entered thru the pipe 6into the cover 5 and pipes 7 and 11 will be compressed by the water andthe water is forced out of the intake sides of the traps 8 and 13 intothe outlet legs'or sides of said traps. The force of the air upon thetop of the column of water in the cover 5 causes the level of thiscolumn to be maintained below the upper end of the pipe 7 'so as toprevent iow of water out thru said pipe. The action of the compressedair maintains the traps with the outlet sides filled and the intakesides practically free of water, the air sustaining the weight of thecolumns of water in the outlet sides of the pipe so that the level ofthe water is at the pipe 9 in one instance and at the top of the passage25, in the other instance. lVhen the flushing tank is filled thepressure of the air on the siphons and traps is balanced by action ofthe weight of the columns of water and head water in the tank itself.Thus upon the slightest disturbance of this balance the flushingoperation will take place. Therefore, upon use of the urinal, some ofthe liquid will run thru the perforated guard plate 16 into the chamber20 whereupon the level of the water A therein will be raised. If thislevel is raised this water is reduced and is not suflicient.

to overcome. the air pressure in the pipe 11. The air then expands anddrives the water out thru the trap 13. Simultaneously with the action inthe trap 13 the trap 8 operates and the air pressure is likewise reducedin the cover 5 whereupon the water will rise in said cover until itflows into the pipe 7. The water of the tank is then free to liow intothe urinal thru the pipes 7 9 and l0, and the pipe 11 and passageway 25.The head of the water in the tank also acts to siphon the tank thru theair intake pipe G and the urinal will be thoroughly flushed and the tankdrained.

Aft-er flushing of the bowl and while the tank 3 is reiilling thechamber 2O will be siphoned several times. When the water is level inthe trap 13,` as is the case immediately after a flushing operation, thelevel of the water in the chamber 2O will have been lowered to the lineof perforations at the bottom of the cover, due to siphoning of thewater therein out thru the passage 27 during the overflow of the pipe 11vwhile the water in seeking its level in theV trap 13. This level in thechamber 2O will be raised during the time required in filling the tank3, by seepage or draining of the small quantity of water collected-onthe sides and bot-V tom of the bowl and due to the water forced out ofthe passage 25 into said chamber while the air is compressed in thepipeV 11 by the action of the water against the air in the cover 5. Vhenthe level of the water in the chamber 2O reaches the level of the topofthe passage 27 the water in said chamber will siphon out thru thepassage 27 and drain the chamber until when the tank 3 is filled and theair compression ceases to force the water out of the passage 25whereupon the level of the water in the chamber is lowered to a 4pointbelow the tops of the passages 25 and 27 and the apparatus is againready for an automatic flushing opertion.

The passages 18, 25 and 27 are straight, substantially upright and inline with the opening 15, when open the plate 16 may be lifted out andready access to these passages and the chamber 2O may be had'in orderto1clean out theserele'mentsl Thusitwill. ibe ,seenl that. those.elementsg requiring cleaning from time to: 4time may:` be. reached andcleaned without. disassembling Lthe ap.- 5- paratus and requirin ltheemployment ofa,

A nut`35 holds the pipe lin place anda drain pipe 36 of usual form is connected to the lower end of the pipe34.

A partition 37 integral with the pipe 34 on one side'thereof and with ahorizonal bottom member 38, forms withthe wall of the pipe 34-.andmember 38, a chamber' within the pip@ 34. The upper edge of this chamberat the partition side terminates short of the upper end of thepipe 34and allows for overflow into the pipe 34. The upper end of the pipe 34supports a perforated guard or screen plate 31-whichis removablycountersunk in said upper end. A pipe 41 leads from the upperv trap, notshown, (which trap corresponds to the trap 8 and the pipe to the one 11of the preferred form ofthe invention), thruopenings 42l and 43 in theside of the pipe 34, up into the chamber 39. A pipe 44 extends fromv4the chamber 39, thru the bottom 38 and discharges into the pipe 36. Thepipes 41 and 44 are substantially upright' in Vthe-chamber 39 and havetheir upper ends open in the same horizontal plane at a point near butslightly below the upper end of the chamber. A cover member45 closed atits upper end is mounted in the chamber vso as to' house the upperportions of the pipes 41 and 44, the upper ends of said pipesbeingspaced slightly below the closed end ofthe cover.
